WATER-SEPARATING FILTER FOR GASOLENE.

Specification of Letters Patent.

Patented Dec. 9, 1913.

To all 'whom it may concern.'

Be it known that I, CHARLES A. ENTORF, citizen of the United States, residing at Amboy, in the county of Lee and State of Illinois, have invented certain new and useful Improvements in lVater-Separatlng F11- ters for Gasolene, of which the following is a specification.

My invention relates to filters and particularly to filters for filtering gasolene, naphtha and similar liquids.

The primary object of my invention is to provide a filter whereby water may be separatedfrom gasolene or like liqulds when 1t is being poured through the filter. 0

A further object of the invention 1s to provide a filter, the body of which has a plurality of openings at various levels leading into a collecting duct whereby the water which may have accumulated in t-he lter at various levels may leave and Separate from A further object is to provide a construction of this character with a plurality of fine meshed filtering screens, which will act to detain the water above the screens and to provide in connection with these screens a water duct having openings leading into the filter below the screens whereby any water which may pass through the screens will pass out into the water duct and may be separately discharged.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings wherein: Y

Figure 1 is a perspective View of my 11nproved iilter. Fig. 2 is a vertlcal dlametrical sect-ion, the section being taken through the duct 12. Fig. 3 is a plan vlew of the same.

Corresponding and like parts are referred to in the following description and illustrated in all the views of the accompanying drawings by the same reference characters.

As Villustrat-ed the body of the filter is formed by a funnel-shaped receptacle designated generally 2. This receptacle has a downwardly converging conical side wall 3 which at its upper end merges into 'a vertical wall 4. This vertical wall at its upper end is formed with a beadand inte al with this bead is a downwardly and mwardly extending, nearly annular splasher 5.

Projecting through the lower end of the conical portion 3 is a tubular discharge duct 7. It will be noted from Fig. 2 that this discharge duct extends upward above the lower end of the conical portion 3 for a purpose that will be later explained, the upper end of the discharge duct bein screened by a cap 8 preferably formed o ne meshed wire gauze. Disposed at intervals across the conical portlon of the filter are a plurality of tine meshed wire gauze screens designated 9 and 10 respectively.

Formed at the lower end of the body of the l lter is a water collecting chamber designated 11 which is also conical in form and is fastened at its upper edge to the face of the conical portion 3 and soldered or otherwise fastened at its lower edge to the outer face of the duct 7. Extending'down one side of the body 2 is a water receiving duc-t 12 fo-rming a drain and vent pipe. This duct extends above the upper end of the body 2 and at its lower end opens into the chamber 11 so that the member 12 practically forms a duct leading from the chamber 11. This duct 12 communicates with the interior of the body 2 at a plurality of points by means of perforations 13, 14 and 15. The perforation 13 isdsposed just below the beaded upper edge of the body 2, the perforation 14 is disposed just below the screen 9 while the perforations 15 are disposed at the lower end of the conical portion 3, that is7 below the upper end of the duct 7.

The operation of the invention is as follows: lVhen gasolene, naphtha or like iuids which contain water are poured into the filter, the gasolene will pass through the wire gauze screens 9 and 10. As soon, however, as the wire gauze 9 is wet with kerosene or gasolene, it is nearly impossible to get any water through it, and the same, of course, applies to the wire gauze 10. yAny water which may pass through the screen 9, however, but not pass through the screen 10 will pass into the duct through the opening 14. If, however, any water passes through the screens 9 and 1() into the space below the screen 10, the water being so much heavier than the kerosene or gasolene will .and will pass into the reservoir 11 by way of the perforations l5. It will be noted j that the tube or duct 7 extends far enough above the openings 15 so -that no heavy liquids will reach the screen 8 and so that only the gasolene will pass through' the screen and the water and other heavy liquids will pass .out through the perforation 13. After the gasolene has been passed through the filter, the water collectlng chamber l1 may beemptied by simply tipping the'filter to the side on which the drain or vent pipe is'located and everything that is in the filter reservoir will pass ofi' through the drain or vent pipe 12 and any water that may be caught in the upper portion of the filter will pass out through the open'- ing-13 or be caught in the projecting portion of the drain pipe.

While I have illustrated what I believe to be a thoroughly effective form of my invention, it will of course be understood that it might be modified in many ways without departing from the spirit of the invention,

and that itl may be made in various sizes and shapes as will best accommodate it to any special work to be done.

What 'I claim is: 1. A filter' of the character described in cluding a hollow body, a discharge pipe leading from the hollow body and having its inlet opening disposed above the bottom 0f said body, a plurality of filter screens extending horizontally across the hollow body, the inlet end of the discharge pipe being also provided with a filtering screen, and a receiving duct forming a drainage passage and' communicating with the hollow body at the bottom thereof below the level of the inlet end of the discharge pipe and with the hollow body above each screen of the series.

2. A filter of the' character described including a hollow body, a discharge pipe leading from the hollow body and extending above the bottom thereof, a vplurality of filtering screens extending horizontally across the hollow body, the upper end of the discharge pipe being also provided with afltering screen, and a water duct forming a drainage passage and communicating with the hollow body at the bottom thereof below the level of thel upper end of the discharge pipe and with the hollow body immediately below the first screen of the series and near the upper end of the hollow body.

3. A filter of the character described including a hollow tapering body, a discharge the body, and a receiving chamber carried at one side of the hollow body, said chamber having an opening leading into the interior of the hollow body and said opening being spaced a distance above said screen, said chamber also having an opening leadthe upper endof Yforming a passage and extending from the water collecting chamber along the side of the hollow body and above the same and having an opening into the hollow body immediately below the rst screen of the pair and also having an opening into the hollow body near the top thereof.

5. A filter of the character described com-V Vterial covering the top of the discharge pipe,

a water collecting chamber surrounding the discharge pipe and disposed at the lower end of the conical receiver, said chamber -communicating with the interior of thereceiver at a point below the'upper end of the discharge pipe, and a water' duct leading from the collecting chamber and at'- tached to the walls of the receiver and open at its upper end, andnpper and lower. filtering screens arranged within the' conical portion of the receiver and in spaced relation to each other, the wall of the receiver vhaving an opening at its upper end leading into the upper portion of the duct, andan opening disposed below the first screen of the series leading into said duct.

6. A filter of the character described comprising a circular body having a conical lower portion and having an vinwardly extending splasher flange at its upper end, a discharge pipe projecting into the receiver at the lower end thereof and extending above the bottom of the receiver, a filtering cap attached to the upper end of the discharge pipe, a water receiving chamber atl tached to the lower end of the receiver and surrounding the discharge pipe, the wall of the receiver being perforated at its lower end below the discharge pipe leading into said water receiver, an upper and a lower screen disposed .within the conical portion of the receiver in spaced relation to each other, and a duct leading from said water being disposed at the cutaway port-ion of the splasher flange.

7. A filter of the character described comprising a hollow downwardly tapering body, a discharge pipe entering the lower end of the hollow body and concentric with the longitudinal axis thereof, the upper end of the discharge pipe being disposed above the lower end of the hollow body, a filtering screen forming a cap closing the upper end of the discharge pipe, a plurality of filtering screens extending horizontally across the hollow body in spaced relation to each other, a receiving and collecting duct carried by the hollow body and open at its outer end, 15
